IVILLIAM H. TAPPEY, OF PETERSBURG, VIRGINIA, ASSIGNOR TO TAPPEY 8L STEEL, OF SAME PLAGE.

COTTON AND HAY PRESS.

SPECIFICATION forming part of Letters Patent No. 340,164, dated April 20, 1886. Application tiled February 18, 1886. Serial No. 192,364. (No model.)

yTo all whom it may concern.-

Be it known that I,- WILLIAM H. Tnrrnv, a citizen ofthe United States, residing at Petersburg, in the county of Dinwiddie and State of Virginia, haveinvented certain new and useful Improvements in Cotton and Hay Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to 1o which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to cotton and hay presses, and is an improvement on the press shown and described in Letters Patent granted to myself, Alexander Steel, and Charles J. Beasley on the 15th of June, 1875, No. 164,608.

2o In these Letters Patent means are described for automatically throwing the mechanism' that operates the platen or follower out of gear when said follower has reached a certain point in its downward movement. The auto- 2 5 matic shifting of the stop-lever to arrest the downward motion ofthe platen takes place when the latter reaches the upper edge of the doors, or is about to reach the upper edge of the doors, ofv the compressing-box, to prevent 3o injury thereto or to other operating parts of the press, by reason of any inattention on the part of the operator to stop the movement of the platen in proper time.

The object of this invention is to provide means for automatically shifting the stop-lever and throwing the gearing that operates the follower out of operation a second time, practice having demonstrated that by givingthe material to be compressed a further compression after the doors have been removed a covering can be more readily sewed around said bale, ample space being` afforded when said doors are down. On the other hand, the removal of the bale from the -press is greatly facilitated by this' further compression, for the reason that the bale may be tied more securely or tighter to avoid too great an expansion of the bale, that usually renders its removal from the press very difficult. To these ends I arrange upon one of the nuts that actuate the platen or follower a second lug or projection, whereby the stopleveris shifted a second time t0 throw the platen-operating mechanism out of operation. By means of this arrangement, when the platen has reached the proper point in its downward movement, the stop-lever is shifted, and the mechanism that operates the platen is thrown out of gear. The end doors are thus removed, and the stop-lever is shifted to throw the platen-operating devices into gear 6o again land give the bale a further compression. The extent of this second compression will depend'upon the location of the second lug or projection on the nut, and in practice I have found that a range of motion of about six inches (more or less) will be sufficient, when the said second stop will again shift the stoplever automatically to throw the platen-operating mechanism out of gear. The covering may now be sewed on or the bale may be 7o tied, or both, without danger of too great expansion, and the bale may be readily removed from the compressing-box.

In orderv to enable others skilled in the art to which my invention appertains to make and gearing with the driving-shaft G, on which is the shifting band-pulley D, having its hub provided with clutches for adapting it to engage 9o with collars on each side thereof fixed on the shaft, all as described in the patent above referred to.

That portion of the end casing or box of the press immediately opposite the end ofthe bale is made in a separate piece or door, E, the lower end ofwhich is held in place by a crossbar, c, in the frame, while the upper end is clamped to the side door, G, bya link or strap,

b. One end of this link is attached to the end Ico door, E, the link passing across the corner at an angle of about forty-live degrees, and the other end passing over a suitable projection, d, on thebar of the side door, G. These straps or links being at all four of the corners and the pressure against all four of the doors, it is evident that the straps or links will hold all the doors in position.

When the doors are to be removed, the ends of the links Z1 are removed from theprojections d, which at once puts the doors at liberty.

H represents the shifting-lever, on which is pivoted a finger, I. The outer end of this finger is made heavy enough to overbalance the inner or upper end ,which will cause it to stand in the position shown in Fig. 1. The upper end of the finger Iis forked, as shown at e.

.l is the follower, attached to the nuts K K on the screws B B by means oflinksf,which turn on projections t' on the nuts, the upper ends passing over suit-able projections, on the follower. These straps or links may be turned back off of theprojections rv, to disconneet the :follower for removal to ll the case.

Through the lower end of the finger I is passed a set screw, m, the point of which touches the lever H, and thus serves to set the finger to the required position.

The operation of the press may be brieiiy described to be as follows: The box having been filled withthe material to be compressed, and the follower placed in position, with the links f in engagement with the nuts K, and

supposing said follower to be in the position shown in Fig. l, the outer clutch-face,d,on the driving-pulley D being in engagement with a clutch-face, c, on the driving-shaft, if,'now, the pulley D is 'rotated in the direction of the arrow on shaft C, the latter, through the fast pinions p p', will rotate the bevel-wheels w w', and through the latter the screw-rods B, to canse the nuts K to run down on said rods with the follower J. When the latter reaches the desired point above the removable box ends and sides, the lug h will bear on the finger I and tilt the lever H, so as to disengage the clutch-face d from the clutch-face c, said pulley running idle on the shaft C. The doors are now removed, and the lever H moved so that the clutch d of pulley D will again engage the clutchcon shaft G. The follower will again be moved downward to compress the bale until the lug h comes in contact with thefinger I,to disengage the clutch d on the driving-pulley from that c on the drivingshaft and arrest the further downward movement of the fol lower. The covering may now conveniently be secured on the bale or the said bale tied,or both, when the lever H is manipulated to engage the inner clutch, d', on pulley D with the clutch c on loose bevel-.pinion C on shaft C. The latter pinion will now rotate the shaft in a reverse direction to that shown by the arrow, and also the screw-rods B, whereby the nuts, with the follower,will run upward, as will be readily understood. As soon as the follower is out of contact with the bale,the latter may be readily removed, and when the follower has reached the limit of its upward motion the clutch d is disengaged from that c by means of the shifting-lever, and may then be removed from the screwrods,and the box filled again, as will be readily understood.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, with the shifting-lever H, of the finger I, pivoted thereto and forked at its upper end, and the projections h and h',

-formed on the nut K, substantially as and for the purposes herein set forth.

In testimony whereof I aiix my signature in presence of two witnesses.
